Claims. (Cl. 198-12) The above invention refers to an arrangement forlifting, removing and loading of mass-goods, such as sand, gravel,grain, snow etc. comprising a driven paternoster mechanism, equippedwith shovels, digging scoops, spades or the like equipment, arranged oneafter the other and driven by endless chains, wires or the like elementsmounted movable around an oblong frame, preferably with rounded-offcorners. This frame can most advantageously be arranged resting ontransporting wheels.

' The frame is adjustable into difierent inclined positions relative theearth. The shovels are arranged to move upwards along the upper sides ofthe inclined frame and downwards along its lower sides turning around atboth ends of the frame.

The device according to the invention is mainly characterized by thefeature that the shovels of the elevator are mounted on a shaft at eachside of the shovels, said shafts having two transversally projectingguide-pegs provided with rolls and being arranged to catch into twoendless channel-formed guide-tracks on each side of the frame, so thatthe shovels during their motion around the frame will be guided by saidtracks. The tracks are bent at the lower end of the frame in such a waythat the shovels here will be pushed into the goods to be lifted,parallelly to the ground surface and only thereafter be lifted uptogether with the goods and transported to the upper end of theaternoster device substantially maintaining their position as to theground, where the shovels are being tilted over and the goods thusemptied.

The accompanying drawing shows schematically one of the embodiments of adevice according to the invention, viz.:

Fig. 1 shows a side elevation view of the device, with a side wallremoved,

Fig. 2 shows the device seen from the front, and

Figs. 3 and 4 show a shovel element in a larger scale in front and sideelevation.

The frame of the device comprises two parallel plates 1, the ends ofwhich are rounded. At both of the ends of the frame are axles 2 and 3arranged with cog-wheels" 4, 5, around which the driving chains 6 of thepaternoster device are arranged to travel.

The frame 1 rests on a support '7 with wheels 7a. At the lower end ofthe frame is an adjustable stand with wheels. For driving thePaternoster device there is arranged in the frame a motor 10. The motor10 transmits power to the driving chain 6 over the cog-wheel 11, thechain 12, and the cog-Wheel 13 on the upper cogwheel 4. By means ofanother chain 14 running over the cog-wheel 15 connected to thetransport wheel 7a the complete device may be moved by .the motor 10.

On the inner side of each of the side walls of the frame there arearranged two U-formed irons serving as guidetracks 16 resp. 17 for therolls 20, 21 of the shafts 19 of the shovels 18 of the paternosterdevice. Each shaft has two sidewardly projecting guide-pegs, the oneplaced at the end of the shaft, the other at the middle of the shaft.These pegs carry the guide-rolls 20, 21 which of the device.

suitable container.

2,920,136 Patented Jan. 12, 1960 l are adapted to run inside and alongthe aforesaid guidetheir length mutually parallel. At the end of theframe the outer track is running as a circular arc, while the innertrack is bent according to a special form, for the purpose of-adjustingthe motion of the shovel shaft so that the shovels at the lower end willperform a digging motion into and parallelly relatively the groundagainst the goods intended for transport. Only hereafter they will belifted upwards and transported to the upper end During the movement theshovels will substantially maintain their inclined position relativelythe ground. The shovel shafts are steered by both of the steering.tracks thus, that during the downward motion of the shovels towards thegoods, the inner roll 20 of the shovel is in its moving directionfollowing after the roll 21 running in the outer track. When the shovelsare passing the lower end of the frame, the mutual position of the guiderolls will be reversed in such a way that, whilethe shovels are movingtowards the upper end of the device, the inner roll 20 of the shovelswill be running in front of the outersteen'ng roll 21, as shown inFigure 1.

The device canbe arranged so that it will empty the lifted goods'into atruck, a railway wagon or into some The shape of the shovels can alsovary in different ways, depending on the kind of. work that the deviceis made to perform. For'ex'ample, in-

stead of shovels there can be used forks; or the like.

elements, whereby the device can be used for digging up potatoes and toplace these into a sorting or a storing container.

The device according to the present invention is not limited to the formof construction shown in the drawing. It can be completed and varied indifferent ways without departing from the spirit and scope of theinvention. It is for instance possible to substitute the motor 10 with atransmission axle receiving its driving power from a separate powerresource, for instance a tractor.

What I claim is: p I

1. A material lifting device, comprising an endless travelling chain,scoop elements coupledto said chain, an outer continuous guideway, aninner continuous guideway cooperatively associated with said outerguideway, a first pair of rollers for and operatively associated witheach said scoop element and cooperatively associated with said outerguideway and a second pair of rollers coupled to each said scoop elementand cooperatively associated with said inner guideway for the continuouscontrol of each of said scoop element as it is moved in a cycle by saidendless travelling chain from a material loading position to a materialdiscarding position without any loss of material therebteween and againto the material loading position to recommence the cycle, said inner andouter guideways comprising guide-tracks on which said associated rollerstravel, said inner guide-track being substantially uniformly spaced fromsaid outer guide-track between said loading and discarding positions andbeing spaced a distance greater than the uniform spacing at saiddiscarding position and a distance less than said uniform spacing atsaid loading position, which distances cooperate with each said scoopelement in order to position it in said discarding position and in saidloading position and to prevent loss of material when each said scoopelement moves from said loading position to said discarding position.
